VW joins Daimler's protest of new A/C refrigerant as EU deadline for compliance passes

The case of Dupont and Honeywell's refrigerant R-1234yf is doing the exact opposite of keeping things cool. The two chemical companies have spent years and hundreds of millions of dollars developing R-1234yf to replace R-134a, the new refrigerant shown to be 99.7-percent kinder to the environment than the one it is meant to succeed. Part of that development has been years of testing by governments, outside safety agencies and automakers to approve the chemical for use in cars. It passed the protocols necessary for the European Union to declare that new and significantly revised cars from 2013 onward needed to use R-1234yf, and mandated that every car as of 2017 must use it.
Enter Daimler AG. The automaker created a head-on collision test with a B-Class at their Sindelfingen test track that would lead to the pressurized refrigerant being sprayed on the engine. The result in 20 out of 20 test was that the refrigerant burst into flames as soon as it hit the hot engine, while Daimler says that R-134a does not catch fire in the same test. Another unexpected result of the R-1234yf test was the release of hydrogen flouride, a chemical far more deadly to humans than hydrogen cyanide, emitted in such amounts that it that turned the windshield white as it began to eat into the glass.
Said a Daimler engineer in a Reuters piece, "It was scarcely believable. The most complicated lab tests conducted using the most sensitive measuring instruments around found nothing and all we do is drive a car around a couple of times, open a tiny hole in the refrigerant line and the next thing you know the car is on fire." So Daimler said it wouldn't use the refrigerant, and it recalled the cars it had already shipped with R-1234yf.

VW considering single, cheaper li-ion cell for all plug-in vehicle batteries

Volkswagen is finding rapid success in the battery electric vehicle market; especially in Europe where the e-Golf is already the segment sales leader. Recent concepts like the C Coupe GTE, Sport Coupe GTE and Cross Coupe GTE suggest more plug-in hybrids from the company are on the way, too. To make future models more economical, the German automotive giant is considering switching to a standard design for its lithium-ion battery cells. Using standardized parts is a long-accepted principle in production because it leads to economies of scale, and a company can pass on the savings to buyers or pocket the money to boost profits. VW is aiming for a massive 66-percent drop in costs by switching to a unified design, according to Heinz-Jakob Neusser, the board member in charge of development, to Automotive News. While the cells would be uniform, they could be crafted into different modules to fit each specific model. VW currently buys cells from Panasonic and Samsung for various models, but under the new plan all of the automaker's brands would switch to a single one. "We have a clear understanding in the group of a common cell," Neusser said, according to Automotive News, without suggesting when a change might happen. VW also has a few months decide on a different future for its EVs. The automaker is reportedly considering whether to use sold-state lithium-ion batteries from a US-based supplier for upcoming models. The next-gen tech could potentially give a massive boost in range while also being fireproof.

2015 Volkswagen Touran is the Euro MPV exemplified [w/video]

Among the vehicles Volkswagen doesn't sell in the United States, we retain a soft spot for the tiny Touran MPV. Five doors, a reasonably sized trunk, clean sheet metal and an attractive cabin is an appealing combo, after all, regardless of the form factor. For the 2015 Geneva Motor Show, VW updated the popular compact van for European audiences. Like the Golf-inspired styling of the second-generation model, the popular hatchback's looks are clearly evident in the third-generation Touran. The Golf's small upper character line is more dramatic on the van, although the general taillight and headlight shapes are remarkably similar. The grille, meanwhile, is more Passat than anything else, with a conservative three-bar design. The R-Line model gets more dramatic front and rear bumpers, with black accents on the former and a pair of chromed exhaust tips jutting out underneath the latter. The cabin is typical of Volkswagen, with handsome materials throughout. Piano black is the dominant accent material, found on the dash and steering wheel, while the leather-wrapped steering wheel and hide seats both look like nice enough. Check out our full gallery of images of the new, third-generation Touran from the 2015 Geneva Motor Show. Volkswagen presents the new Touran - Germany's best-selling MPV completely redeveloped - More room; smart new design - New engines up to 19 per cent more economical Volkswagen presents the new Touran. The completely redesigned MPV was showcased before an audience of international media representatives at the Autostadt in Wolfsburg, not far from the production site where the popular family car is made. The interior of the new model has undergone a significant increase in size and is highly configurable. Refinements have been made all around the vehicle, which boasts a range of six new economical engines and an extensive line-up of assistance and infotainment systems. The public premiere of the new Touran will take place in the coming week at the Geneva motor show. Prof. Dr. Martin Winterkorn, Chairman of the Board of Management of Volkswagen Aktiengesellschaft, explained: "As one of the most successful family cars in the world with 1.9 million units sold, the Touran is indisputably Germany's top MPV.
